CERN Accelerating science

The CMS collaboration has measured the speed of sound in the quark–gluon plasma more precisely than ever before, offering new insights into this extremely hot state of matter

In cooling positronium with laser light for the first time, AEgIS may also have taken the first step towards a matter–antimatter system that emits laser-like gamma-ray light

The results imply that climate models are underestimating the formation rates of aerosol particles

New ALICE measurements shed light on the dynamics of charm and beauty particles in quark–gluon plasma

During the LHC era and on the cusp of the High-Luminosity LHC era, theoretical and experimental physicists are already using precision calculations to find the smallest deviations that might reveal new physics

CERN and the Accelerator Laboratory in Jyväskylä, Finland, have teamed up to weigh in on the understanding of the effects of the weak force on quarks

The ALICE collaboration presents its first results based on data collected with the upgraded detector in 2022, the first year of Run 3 of the LHC, at the 2023 Quark Matter conference

The ATLAS collaboration sets stringent limits on the existence of supersymmetric dark matter particles

ATLAS experiment places some of the tightest limits yet on magnetic monopoles
